Abstract
In a method for controlling the speed of a vehicle, a future traffic situation is predicted as a function of the acceleration of the controlled vehicle. The future traffic situation is then evaluated with a cost function which is defined in such a way that its value increases with the number and relevance of the other vehicles which are traveling in front and are relevant to the controlled vehicle. The value of the acceleration which minimizes the cost function is then determined as an acceleration setpoint value, and the acceleration of the vehicle is adjusted to this value.

A method for controlling the speed of a vehicle taking into account other vehicles that are traveling in front and whose respective position and speed are determined with respect to the controlled vehicle as movement parameters, said method comprising:
- (a) predicting a future traffic situation by reference to the movement parameters of the other vehicles which are traveling in front, as a function of the setpoint acceleration of the controlled vehicle, which can be predefined as a free parameter;
- (b) evaluating the future traffic situation by reference to a cost function whose value increases with the number and relevance of the other vehicles that are traveling in front, and are relevant to the controlled vehicle;
- (c) determining an acceleration setpoint value of the controlled vehicle for which the cost function assumes a minimum value;
- and
- (d) adjusting the acceleration of the controlled vehicle to the acceleration setpoint value.
